
Dataset description
The dataset consists of different data from a fine blanking experiment, where roller leveler parameter were varied.  In the experiment a Feintool XFT 2500 speed with an integrated roller leveler was used to process a coil of the material 16MnCr5. The nine different settings can be found in Table 1. For every setting over 100 parts were produced. Every tenth stroke parts were extracted and measured with a Barkhausen noise sensor.

For every fine blanking stroke of the experiment there are signals from eight different force sensors. Four sensors measure the punch force, three sensors measure the blank holder force, and one sensor measures the counter punch force. For every of the nine settings there are 100 strokes of each sensor saved in a pickle file. Each pickle file contains one data frame for each sensor with the times series of the stroke as column. 
Each CSV-file corresponds to one Barkhausen noise measurement. The actual measurements begin in line 15 of the files. Each data line consists of two values, namely the time in seconds starting from zero and the Barkhausen noise value. The values are separated by semicolons. Commas are used as decimal separators. The lines above the data describe meta data that were automatically generated by the sensor (e.g., time of measurement and sample frequency).
The Barkhausen noise measurements are complimented by an Excel file “mbn_measurement_protocol.xlsx". This file allows to map the enumerated Barkhausen noise measurements to the different leveller settings. For example, measurement 87 corresponds to the last Barkhausen noise measurement for the first sheet leveller setting and measurement number 88 corresponds to the first Barkhausen noise measurement for the second sheet leveller setting. For each leveller setting, approximately 30 parts were sampled. For each part, three consecutive Barkhausen noise measurement were performed. The column "Workpiece" allows to infer the number of parts sampled per leveller setting. For example, there were 29 parts for the first setting and 33 parts for the second setting. Some measurements deviate from their expected appearance for different reasons (e.g., pure noise or signals being too short). These measurements also listed in the Excel sheet and marked as "bad measurement" in the column "Note".
